The best way to help smartphone users manage their screen time may be to make phones progressively more annoying to use, according to new U-M research. Delaying a phone’s swiping and tapping functions forces users to think harder, making it easier for them to consider whether to keep scrolling.

Using human cells in laboratory rats, Michigan Medicine researchers have developed a functional model of thoracic aortic aneurysm, creating new opportunities for understanding disease development and treatment. No treatments currently exist for the condition, which is a weakening and bulging at the body’s largest blood vessel in the chest.  

New chemistries for batteries, semiconductors, and more could be easier to manufacture, thanks to a new approach to making chemically complex materials that researchers at U-M and Samsung’s Advanced Materials Lab have demonstrated.

Insights could lead to treatments restoring ovarian hormone production and the ability to have biologically related children, according to U-M engineers. Researchers could potentially create artificial ovaries using tissues that were stored and frozen before exposure to toxic medical treatments such as chemotherapy and radiation.

With 5,000 tiny robots in a mountaintop telescope, researchers can look 11 billion years into the past. Now, using the largest 3D map of our cosmos ever constructed, the Dark Energy Spectroscopic Instrument reveals the most precise measurements to date of how fast the universe has expanded throughout its history.

Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly. While such disks have been imaged, just two planets have been caught in the act of forming so far. Astronomers are now aiming the James Webb Space Telescope at protoplanetary disks to find clues about the ways in which planets form, and how they influence their natal disk.

The first stem cell culture method that produces a full model of the early stages of the human central nervous system has been developed by a team of engineers and biologists at U-M, the Weizmann Institute of Science, and the University of Pennsylvania. The model, which resembles all three sections of the embryonic brain and spinal cord, could shed light on developmental brain diseases.

For the first time, load-bearing structures like bridges and shelters can be made with origami modules — versatile components that can fold compactly and adapt into different shapes. It’s an advance that could enable communities to quickly rebuild facilities and systems damaged or destroyed during natural disasters, or allow for construction in places that were previously considered impractical, including outer space.

When Italy’s Mount Vesuvius erupted in AD 79, it buried the palatial villa of Lucius Calpurnius Piso Caesoninus, Julius Caesar’s father-in-law. These black and brittle papyri may look like charred croissants, but U-M classicist Richard Janko believes they contain lost masterpieces of literature, history, and philosophy.
